Abstract: A repeater for maintaining wireless line of sight communications. The repeater is autonomously repositional in both absolute location and azimuthal orientation. The repeater has at least two vibratory motors, or other vibration sources, which provide oscillations to depending legs against a support surface. By selectively operating one or more of the vibration sources together or independently, the repeater may be moved as helpful to maintain line of sight communication with another repeater or other operational hardware. A command signal from a remote base station controls the locomotion of the repeater to provide both a change in absolute position relative to the surroundings and a rotational change in azimuthal orientation as necessary to maintain communication under dynamic conditions.

Abstract: A unique cooling system for an aircraft is designed to provide extremely low temperature cooling airflow. The system includes an air source, a first system compressor and a second system compressor positioned in series for compressing and heating the air. A least one heat exchanger can be used to cool the air at predefined locations. A condenser for condensing water out of the air is positioned downstream of the second compressor. The water can be removed with a water separator and at least a portion of any remaining water in the form of liquid or vapor is removed from the air in a membrane dehydration device. The air is expanded in at least one system turbine to bring the air temperature to a subfreezing temperature. The subfreezing air is then used to cool electronic components and mechanical components within the aircraft.

Abstract: A micro-cavity passive actuator is configured to delay dynamic stall of an airfoil. The micro-cavity actuator is formed in the pressure sidewall surface proximate the leading edge of the airfoil. This cavity remains essentially inactive at low incidence. However, as the wing's effective angle of attack dynamically increases and the stagnation point displaces past the micro-cavity, the accelerating flow grazing the cavity induces a high-frequency resonance phenomenon (known as Rossiter modes). The self-generated small-scale disturbances are carried around the leading-edge through the boundary layer to the wing's upper side where the laminar separation bubble (LSB) amplifies these disturbances. This process delays LSB bursting and dynamic stall. The micro-cavity must be sized such that its naturally emitting oscillations are in a range of frequencies that can be amplified by the LSB.
